#108259 - Relay ratings Responding to: ???'s previous message |
Abdul Ghafoor said:
can i operate AC current 220v using the 12v relay using this circuit Diagram. A relay should be considered as 2 entirely separate elements: 1 The coil.. This is what operates the contacts; ie, causes them to open and close (switch on & off). This is the only thing of concern to your microcontroller - so long as the relay's coil ratings are suitable to the circuit, the microcontroller can drive it. 2. The Contacts This is what actually controls the load You just need to pick a relay with a suitable contact rating for your load! |

| Just search for, "Relay" !! | 01/01/70 00:00 | |

| ULN2803,ULN2003 | 01/01/70 00:00 | |
| more on relay ratings | 01/01/70 00:00 | |
| Yes of course | 01/01/70 00:00 | |
| internal diodes | 01/01/70 00:00 | |
| ULN2003's doesn't easily burn | 01/01/70 00:00 | |
| Uce saturation voltage is rather high | 01/01/70 00:00 | |
| there is an alternative, search for it | 01/01/70 00:00 | |
| I agree | 01/01/70 00:00 | |
| That is bad design | 01/01/70 00:00 | |
| ULNs resist more... | 01/01/70 00:00 | |
| I would never suggest 74HC buffers for d | 01/01/70 00:00 | |
| Yes , you didn't | 01/01/70 00:00 | |
| I would like to see where that is, pleas | 01/01/70 00:00 | |
correct link | 01/01/70 00:00 | |
| Bad Design? | 01/01/70 00:00 | |
| naah | 01/01/70 00:00 | |
| Also depends on transistor speed | 01/01/70 00:00 | |
| valid issue, but not that, now another | 01/01/70 00:00 | |
| Indeed | 01/01/70 00:00 | |
